Abstract (en)

[origin: WO2014118630A1] Cover flux devices and methods are shown. Methods and devices are shown such that, as a solidification front moves from a cooling surface of a mold towards a surface of molten silicon substantially opposite the cooling surface, impurities are driven out of the solid silicon and into the liquid to react with a flux layer on the silicon.
